Severity: normal

I observed a linkage dependency on libsystemd. This was unexpected for me
since I wouldn't expect a package manager depend on it. A package manager should
be as lean as possible.

Having reviewed the code, the only function using libsystemd is used to talk on dbus 
to inhibit system shutdown. Something which will work for systemd only.

Would it make sense to use dlopen() to dynamically load libsystemd when needed
and avoid the hard dependency on libsystemd? If systemd is installed, libsystemd
will be available anyways.

Andreas,

Thanks for this.

You are quite right that this dependency would be much better avoided.

I am interested in us fixing this in ceres/chimaera.

I know you have patched version 1.8  to remove libsystemd0. Would you care to
update that for the current ceres/chimaera version 2.0.1? We can then look at
including it in devuan-packages.

Thanks

Mark

Package: apt
Version: 1.8.2
Severity: normal

I observed a linkage dependency on libsystemd. This was unexpected for me
since I wouldn't expect a package manager depend on it. A package manager should
be as lean as possible.

Having reviewed the code, the only function using libsystemd is used to talk on dbus 
to inhibit system shutdown. Something which will work for systemd only.

Would it make sense to use dlopen() to dynamically load libsystemd when needed
and avoid the hard dependency on libsystemd? If systemd is installed, libsystemd
will be available anyways.
